Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine medical device technology, specifically relating to an acupoint therapy device for assisting in improving ischemic heart disease. Background Technology

[0002] In traditional Chinese medicine acupuncture, many critically ill heart disease patients have achieved clinical therapeutic effects through acupuncture at specific acupoints when other medical interventions are unavailable. Even today, doctors in traditional Chinese medicine clinics still use acupuncture to treat many common and complex diseases, as it remains one of the most effective non-drug treatment methods. There is an acupoint on the palm of the hand, the Laogong acupoint, which belongs to the Pericardium Meridian of Hand-Jueyin. According to the theory of meridians in traditional Chinese medicine, the Laogong acupoint can relieve angina pectoris. Current medical textbooks record that in emergency situations where angina pectoris symptoms occur and no medical facilities are available, strong stimulation and massage of the Laogong and Neiguan acupoints can be used for emergency treatment. Acupuncture acupuncture has long been a primary treatment method chosen by physicians for sudden cardiac events. In times when medical technology was less advanced, acupuncture played a vital role in treating heart diseases. Different physicians have varying treatment abilities. A crucial aspect of the acupuncture process is the manipulation of the needle; the frequency and pressure of this manipulation determine the therapeutic effect, requiring extensive experience from the practitioner. The ability to perform acupuncture is something that can be acquired through practice. However, due to various factors, the experience has been lost, and nowadays, the therapeutic effect of acupuncture in treating difficult and complicated diseases is far less than in the past. With the rapid development of modern medicine, there are more and more drugs or surgical options available for myocardial ischemia in modern clinical treatments, and the effects are more obvious than traditional treatment methods. In addition, the soreness, numbness, distension, and pain caused by traditional acupuncture have brought a great psychological burden and even fear to many patients. Ultimately, not only patients choose to give up traditional acupuncture treatment, but many TCM institutions have also abandoned traditional acupuncture treatment. At the same time, acupuncture treatment also requires a high level of skill from the operator, and it is not possible to perform the operation by oneself. Over time, acupuncture has been deviated from the clinical treatment plan for the adjunctive treatment of myocardial ischemia, and drug treatment has become the mainstay.

[0003] Based on the principle of acupuncture stimulation of acupoints, this research and development technology will make traditional acupuncture treatment more technological, intelligent, and miniaturized. It will use non-drug, non-invasive, and painless techniques to replace traditional acupuncture acupuncture point insertion. It requires no special skills from the operator and causes no pain to the user. Acupoint stimulation can be performed in a relaxed and comfortable state, which can more effectively relax tense blood vessels and help improve myocardial ischemia. Summary of the Invention

[0004] The purpose of this invention is to provide an acupoint therapy device to assist in improving ischemic heart disease. It uses a specific pulse waveform coupled to a ferrite core coil to create a pulsed magnetic field that acts on the Laogong acupoint on the human body, replacing the traditional acupuncture method of acupuncture for the adjuvant treatment of myocardial ischemia. The technical principle is to use the physical characteristics of the pulsed magnetic field generated by spatial coupling to stimulate acupoints in the human body, simulating the sensation of obtaining qi during acupuncture. Under the differential effect, bio-microcurrents with positive and negative charges are coupled in. The bio-microcurrents at a specific frequency induce the permeability of local ions at the acupoints. Under the dual action of the meridians and the nervous system, the exogenous abnormal stimulation signal (microcurrent) is sent to the human brain center and the organ (pericardium) connected to the meridian. When the brain center and pericardium receive the exogenous abnormal stimulation signal (microcurrent), they mistakenly believe that there is a source of trauma to the heart. In order to protect themselves, they activate the heart's external defense mechanism and strengthen the heart's own function, including the function of the coronary arteries. Under the regulation and stimulation of the heart, the vascular endothelial cells release more nitric oxide (NO) vasodilator, causing vasodilation and increasing myocardial blood perfusion to improve the heart's external defense function. This innovative invention is based on the physiological mechanism of the human body's self-repair. It uses pulsed magnetic field technology to stimulate the distal Laogong acupoint under non-invasive and painless conditions. Through repeated stimulation multiple times a day, it can help treat myocardial ischemia, solve the soreness, numbness, distension and pain caused by acupuncture, reduce the psychological burden on patients, reduce the technical requirements of operators, and allow users to complete the treatment independently. It simulates the acupuncture technique of traditional Chinese medicine in a non-drug, non-invasive and painless state.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A therapeutic device for acupoint therapy to assist in improving ischemic heart disease includes a therapeutic device body and rings symmetrically arranged at both ends of the therapeutic device body. One end of each ring is hinged to the therapeutic device body, and the other end is a free end, with the free ends of the two rings being movably connected.

[0007] The therapeutic device includes a housing, a battery and a PCB circuit board housed within the housing, and a CPU and a power amplifier mounted on the PCB circuit board. A pulsed magnetic field transmitter is located inside the housing near the palm. The signal output terminal of the CPU is connected to the signal input terminal of the power amplifier, and the signal output terminal of the power amplifier is connected to the signal input terminal of the pulsed magnetic field transmitter. A power switch is located on the housing. The CPU outputs a 3.3V square wave pulse signal, and the power amplifier outputs a 5V square wave pulse signal. The pulse waveform frequency is 40Hz, the period is 25ms, and the duty cycle is 50%. The formula for one cycle of the square wave pulse signal is as follows:

[0008]

[0009] Where U is the maximum value of the waveform, and t is in milliseconds.

[0010] The working process and principle of the above structure are as follows:

[0011] In use, the therapeutic device is worn on the palm of the hand via two straps, which are then connected. It can be used during the day or night while sleeping. The device is placed on the Laogong acupoint in the center of the palm, where a specific intensity of pulsed magnetic field acts, providing adjunctive treatment for cardiovascular diseases. After powering on, the battery powers the PCB circuit board, CPU, power amplifier, and pulsed magnetic field transmitter. The CPU outputs a 3.3V square wave pulse signal. The power amplifier amplifies the input 3.3V square wave pulse signal, outputting a 5V square wave pulse signal. The pulsed magnetic field transmitter receives the 5V square wave pulse signal and, through current coupling in space... The device generates a pulsed magnetic field that penetrates the palm muscles to reach the Laogong acupoint. The CPU central processing unit regulates the operation according to the set time interval frequency, and the device enters automatic treatment mode. The first treatment will begin after one minute, with a countdown of 8 minutes to finish. After 2 hours of standby, there is no pulse waveform output from the CPU central processing unit signal output terminal, no voltage output from the power amplifier, and the voltage value of the pulsed magnetic field transmitter is 0V. Then, the second treatment will begin, with a countdown of 8 minutes to finish, followed by another 2 hours of standby. Then, the third treatment will begin, with a countdown of 8 minutes to finish, and the device will automatically shut down. It automatically performs 3 treatments at night, repeatedly stimulating the Laogong acupoint in the palm, which can improve the auxiliary treatment effect, increase user compliance, and is small and portable, providing a comfortable treatment experience.

[0012] Furthermore, an indicator light is provided on one side of the power switch, and the signal input terminal of the indicator light is connected to the signal output terminal of the CPU central processing unit.

[0013] After the power switch is turned on, the indicator light shows the working status, making it easy for the user to understand.

[0014] Furthermore, the pulsed magnetic field transmitter is an I-shaped ferrite core coil.

[0015] Furthermore, the initial values ​​for the spatial coupling pulse magnetic field strength of the I-shaped ferrite core coil are: 185, 190, 195, 200, 205, 210, 215, 220, 225, 230, and 235 μT.

[0016] Furthermore, the preferred value for the spatial coupling pulse magnetic field strength of the I-shaped ferrite core coil is 210 μT.

[0017] Furthermore, the rings are made of soft silicone, one of the rings has several locking holes, and the free end of the other ring has a buckle that is engaged in the locking holes.

[0018] The straps, made of soft silicone, fit the skin better. The buckles and locking mechanism make it easy to connect two straps together and secure them to the palm of your hand. The different buckle designs make them suitable for people of different body types.

[0019] Furthermore, the longitudinal section of the latch has a T-shaped structure.

[0020] The design of the latch facilitates its engagement with the locking hole.

[0021] Furthermore, a protrusion is formed outward from the center of the surface of the outer shell near the pulse magnetic field transmitter, and the end of the protrusion is arc-shaped.

[0022] The raised design helps to apply local pressure to the palm and facilitates the magnetic field generated by the pulse magnetic field transmitter to pass through the acupoints on the palm, thus achieving a therapeutic effect.

[0023] Furthermore, a charging port is provided on the side of the housing.

[0024] The battery is powered via the charging port.

[0025] Furthermore, the charging port is a Type-C charging port.

[0026] Beneficial Effects: In use, the device is worn on the palm of the hand via two straps connected together. When treatment is needed, the user wears the device on the Laogong acupoint in the palm during the day or while sleeping at night. After turning on the power switch, the battery powers the PCB circuit board, CPU, power amplifier, and pulse magnetic field transmitter. The CPU outputs a specific square wave waveform to the transmitter. This square wave pulse current, coupled through the transmitter, generates a pulse magnetic field that penetrates the palm muscles and reaches the Laogong acupoint. The CPU operates according to the set time interval frequency, and the device enters automatic treatment mode. It can repeatedly and automatically stimulate the Laogong acupoint, resolving the soreness, numbness, distension, and pain caused by acupuncture, reducing the patient's psychological burden, and decreasing the technical requirements for the operator. The user can independently complete the treatment, simulating traditional Chinese acupuncture without drugs, trauma, or pain. This improves the auxiliary treatment effect, increases user compliance, and is compact, portable, and provides a comfortable treatment experience. Attached Figure Description

[0035] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0036] Example:

[0037] like Figures 1-5 As shown, this embodiment provides an acupoint therapy device to assist in improving ischemic heart disease, including a therapy device body and ring belts 1 symmetrically arranged at both ends of the therapy device body. One end of the two ring belts 1 is hinged to the therapy device body, and the other end is a free end, and the free ends of the two ring belts 1 are movably connected.

[0038] The therapeutic device includes a housing 2, a battery 3, a PCB circuit board 4, and a CPU central processing unit 6 and a power amplifier 5 mounted on the PCB circuit board 4. A pulse magnetic field transmitter 7 is located inside the housing 2 near the palm. The signal output terminal of the CPU central processing unit 6 is connected to the signal input terminal of the power amplifier 5, and the signal output terminal of the power amplifier 5 is connected to the signal input terminal of the pulse magnetic field transmitter 7. A power switch 8 is located on the housing 2. The CPU central processing unit 6 is an STM32F030F4P6. The power amplifier 5 is an AD8532ARZ, and the pulse magnetic field transmitter 7 is an I-shaped ferrite core DR1514. The CPU central processing unit outputs a 3.3V square wave pulse signal, and the power amplifier outputs a 5V square wave pulse signal. The pulse waveform frequency is 40Hz, the period is 25ms, and the duty cycle is 50%. The formula for one cycle of the square wave pulse signal is:

[0039]

[0040] Where U is the maximum value of the waveform, and t is in milliseconds.

[0041] The working process and principle of the above structure are as follows:

[0042] In use, the therapeutic device is worn on the palm via two loops 1, which are then connected. When treatment is needed, the user wears the device on the Laogong acupoint in the palm during the day or while sleeping at night. A specific intensity of pulsed magnetic field acts on the palm, which has an auxiliary therapeutic effect on cardiovascular diseases. After turning on the device by pressing the power switch 8, the battery 3 powers the PCB circuit board 4, CPU central processing unit 6, power amplifier 5, and pulsed magnetic field transmitter 7. The CPU central processing unit 6 outputs a 3.3V voltage square wave pulse waveform to the power amplifier 5, and the power amplifier 5 outputs a 5V voltage square wave pulse waveform to the pulsed magnetic field transmitter 7. The pulse waveform current is coupled in space (differential effect) through the magnetic field transmitter to generate a pulsed magnetic field that penetrates the palm muscle tissue and reaches the Laogong acupoint. Processor 6 operates and adjusts according to the set time interval frequency. The therapeutic device will enter automatic treatment mode. The first treatment will begin after one minute and end after 8 minutes. After 2 hours of standby, there will be no pulse waveform output from the CPU signal output terminal, no voltage output from the power amplifier, and the voltage value of the pulse magnetic field transmitter will be 0V. Then, the second treatment will begin, and end after 8 minutes. After 2 hours of standby, there will be no pulse waveform output from the CPU signal output terminal, no voltage output from the power amplifier, and the voltage value of the pulse magnetic field transmitter will be 0V. Then, the third treatment will begin, and end after 8 minutes. The device will then automatically shut down. It will automatically perform 3 treatments at night and can repeatedly and automatically stimulate the Laogong acupoint on the palm, which can improve the auxiliary treatment effect. It is small and exquisite, easy to carry, and provides a comfortable treatment experience.

[0043] like Figure 5As shown, pressing the power switch supplies power to the CPU; the user presses a button, selecting either the treatment mode or the emergency exit mode based on the duration of button contact. The CPU acquires the button contact time and calls different subroutine modules to activate the corresponding mode. In treatment mode, the CPU calls a waveform generation function to generate a 40Hz square wave, with the square wave function expression y(t); simultaneously, it activates a time counter module. When the time count reaches 8 minutes, the CPU shuts off the waveform output, and the software system returns to its initial state, ending the first treatment. The 3.3V square wave output by the CPU is insufficient to handle the load and needs to be amplified. The waveform is sent to a power amplifier to amplify the output power. The power signal then passes through a filter circuit to remove out-of-band noise, and finally, the qualified square wave is transmitted to a pulse magnetic field transmitter to couple a magnetic field to the outside, which acts on the human body for treatment. To ensure the magnetic field strength meets treatment requirements and maintains magnetic field accuracy, a Hall element is used to acquire the magnetic field strength. This signal is sent to the control terminal of the power amplifier to change the output power, forming a closed-loop control to achieve the required magnetic field strength and accuracy. For the emergency exit mode, the main consideration is the safety of the equipment. If an abnormality is detected after powering on, the emergency mode is activated. The CPU sends a control signal to cut off the power supply through a relay to protect the equipment. At the same time, an indicator signal is sent to light up an LED.

[0044] In another embodiment of the invention, such as Figure 2 As shown, the power switch 8 is located on the outer surface of the housing 2 away from the palm. An indicator light 9 is located on one side of the power switch 8. The signal input terminal of the indicator light 9 is connected to the signal output terminal of the CPU central processing unit 6.

[0045] After the power switch 8 is turned on, the indicator light 9 displays the working status, making it easy for the user to understand.

[0046] In another embodiment of the present invention, the pulse magnetic field transmitter 7 is an I-shaped ferrite core coil.

[0047] In another embodiment of the present invention, the initial values ​​of the spatial coupling pulse magnetic field strength of the I-shaped ferrite core coil are: 185, 190, 195, 200, 205, 210, 215, 220, 225, 230, and 235 μT.

[0048] In another embodiment of the present invention, the preferred value of the spatial coupling pulse magnetic field strength of the I-shaped ferrite core coil is 210 μT.

[0049] In another embodiment of the invention, such as Figure 2 As shown, the ring belt 1 is made of soft silicone. One of the ring belts 1 has several locking holes 11, and the free end of the other ring belt 1 is provided with a buckle 10, which is locked in the locking hole 11.

[0050] The ring 1, made of soft silicone, fits the skin better. The buckle 11 and the lock 10 make it easy to connect the two rings 1 together and fix them on the palm. The different buckle 11 settings make it convenient to suit people of different body types.

[0051] In another embodiment of the invention, such as Figure 1 As shown, the longitudinal section of the latch 10 has a T-shaped structure.

[0052] The structure of the latch 10 facilitates its engagement with the slot 11.

[0053] In another embodiment of the invention, such as Figure 1 and Figure 3 as well as Figure 4 As shown, a protrusion 12 is formed outward from the center of the surface of the outer shell 2 near the pulse magnetic field transmitter 7, and the end of the protrusion 12 is arc-shaped.

[0054] The protrusion 12 helps to apply local pressure to the palm and facilitates the magnetic field generated by the pulse magnetic field transmitter 7 to pass through the acupoints on the palm, thus achieving a therapeutic effect.

[0055] In another embodiment of the invention, such as Figure 1 and Figure 3 As shown, a charging port 13 is provided on the side of the outer casing 2.

[0056] Battery 3 is powered through charging port 13.

[0057] In another embodiment of the invention, such as Figure 1 and Figure 3 As shown, charging port 13 is a Type-C charging port 13.

[0058] Medical research shows that the body has a good anti-stress effect when it is in a relaxed state, both mentally and physically. When entering a relaxed state, the sympathetic nervous system is inhibited while the parasympathetic nervous system is excited. This manifests as a decrease in skeletal muscle tone (muscle relaxation), a slowing of respiratory and heart rates, vasodilation, a decrease in blood pressure, and accelerated gastrointestinal motility—all normal physiological phenomena. This clearly demonstrates that tension is detrimental to disease treatment, while a relaxed and comfortable state is beneficial for improving vascular function, promoting blood circulation, increasing myocardial cell activity, and enhancing the normal physiological function of cardiac ejection. The initial intention of this invention is to alleviate pain, slow disease progression, and improve the quality of life for patients with ischemic heart disease during the disease period.

[0059] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
